problem with craftsman 10" radial arm saw

by garymc

lately, I noticed that when I started the saw, it did,t get up to full speed as quickly as it used to. Then one day it just hummed when I flipped the start switch. Trying to rotate the saw blade by hand was difficult. It seemed very stiff. I took the motor apart and cleaned the internal parts (much sawdust) and oiled the spindle. The saw worked fine for a couple days. Then the hum came back when I tried to start the saw, and of course, the blade didn't turn. I ordered a capacitor, and after installation I still had no spin on the blade, but just a hum. I can rotate the saw blade my hand easily. Is there another component that may need replacing ? THIS IS A CRAFTSMAN RADIAL ARM SAW model 113.198111. The motor is 11 amp, 3450 rpm, 1 phase and the motor model # is c48jl-298. By th way, does this model have a reset button ? I don't see one.

Thank you for your question on the radial arm saw not running.

It sounds like the start switch is not on the start contact in the switch and only on the run contact.

I would suggest cleaning or replacing the start switch. You can remove the clear cover off the switch and remove the saw dust in the contacts and burnish the contacts.

Start switch for motor


Remove the blade and blade guard and then tip the motor with the shaft pointing towards the table and locate and remove the screws that secure the to half shell covers on the motor.

Pivot the motor bake and locate the flat motor switch on the end bell of the motor near the fan.

When removing the switch observe the location on the tang from the switch and its location on the centrifugal switch so you can return it to the same area upon re-assembly.

Please let me know how it went.
